Firefox Bookmarklet not working on page https://infosys.beckhoff.com/

[easz]

just casually visited the website and wanted to make some annotations.
https://infosys.beckhoff.com/

and found out that it does not work with Firefox Bookmarklet

it does not work with https://via.hypothes.is neither.

I think this might be the same issue as Firefox Bookmarklet has stopped working on many websites.

I am really excited about the Firefox extension. Follow this to be notified on when it is ready.

This website uses <frameset>, which is an old/obsolete part of the web platform that is not currently supported by Hypothesis. See also hypothesis/h#3113. The original issue was closed but we might be able to reconsider in future if it doesn't complicate the client too much.
